T 0 all whom it may concern:

Be it known that I, ANDREW BEYRLE, a citizen of the United States,residing in the city of Los Angeles, county of Los Angeles, and State ofCalifornia, have made a new and useful Invention in the Art of CasingWooden Moldings and other Forms of Wood with Metal, of which thefollowing is a specification.

Heretofore wooden moldings and other forms of wood have been coveredwith metal by first partially forming the metal for the casing in aseparate machine and reducing the front end of the wooden molding orother forms of wood and then forming the metal up around the reducedfront end so that it would pass through the forming die and thengripping the end of the molding and metal and drawing the same throughthe die. In

thus covering moldings with metal the re-.

duced end which was first put through the die by hand would be ofsmaller size than the other portion of the finished molding and thisreduced end had tobe cut off by hand so that the molding would be ofuniform appearance when used. It takes time to reduce the end of themolding and to form up themetal thereon so that it willpass through theforming die. It also takes time to partially form the metal and there isconsiderable waste both of the wooden molding and the metal to cut offthis reduced end and properly prepare the molding for use, and it takestime so to do.

It is the object of my invention to cover moldings and other forms ofwood with metal so that the strip of molding or other piece of woodandthe metal which is to cover it can be forced through the forming diewithout having any portion of the same reduced in size to unlit it foruse, and which will produce strips of molding or other forms of woodcovered with metal, which strips will be in condition for use as soon asthey pass through the forming die or dies without further preparationexcept to fit the metal on the ends; and to this end it consists in themethod of so securing the front ends of the metal and wood that theywill travel together and then pushing the wood and amctal stripwith'which the molding is to be covered through a die or dies by theapplication of pushing means applied to the rear end of the wood whichcauses .the strip to firmly adhere to the wood and to surround so in uchof theexterior as itis desired to have provided with a metal facing, orcov- Wheels pass a sprocket chain 29.

ering, and in a machine for. so doing. I accomplish this object by meansof the machine described herein and illustrated in the accompanyingdrawings in which;

Figure 1 is the side elevation partly in section of the machine with apiece of molding in place thereon and a sheet of incasing metal beneaththe same with a portion cut away for clearness of illustration. Fig. 2is a plan of the parts shown in Fig. 1. Fig. 3 is a section on the line33 of Fig. 2. Fig. 4

is a detail showing a die forming block. Figs. 5 and 6 are detailsillustrating and showing the adjacent ends of two strips of molding.Fig. 7 is a section on line 77 of Fig. 6. Fig. 8 is a section on theline 88 of Fig. 4.

In the drawings 10 are the side rails and 11 are the legs of the frameof the machine used in carrying out my improved method. Secured to andpreferably upon the side rails at the rear end thereof are guide rails12 which shoe 17 which is adapted to engage the rear end of the woodenmolding 18 upon which is to be formed the metal facing from the strip ofmetal 19. The strip of metal which is to be formed upon'the moldingrests upon the edge turning plate 20 which is rigidly secured upon theforming table 21. This forming table is secured to cross bars 22 whichare mounted upon screw threaded bolts or posts 23 which are providedwithnuts 24 so that the forming table can be adjusted as desired. Mounted ona shaft 25 at the rear end of the machine is sprocket wheel 26, andmounted on shaft 27 at the front of the machine is a like sprocket wheel28 shown in dotted lines in Figs. 1 and 2. Around these sprocket Aconnecting bar 30 is secured by bolt 31 to the push bar table. The endof the connecting bar passes into a slot 32 in the push bar table andthe other endis secured to chain 29 bybeing hooked over one efthe linksthereof. Shaft 25. is mounted in adjustable bearing blocks 33 which areadjusted by screws 34. to take up any slack that is objectionable in thedrivother end of Power is applied to pulley 40 to drive the ing chain;-on shaft 27- are also mounted the front end these edges increase inheight gears 35and 36 which mesh with gears 37 and 38 which are mountedon shaft 39. shaft 39 is mounted at one end 40 and at the other end gear41 which meshes with gear 42 mounted on shaft 43. On the shaft 43 is apower pulley 44.

chain to return the push bar table to the rear end of the machine andpower is applied to pulley 44 ,to drive the chain to cause the push bartable to travel toward the front of the machine, it being understood thepower is al-' ternately applied to these power pulleys to cause thetravel of the push bar table in the direction desired by the opera-tor.

-In the operation of my machine the push bar and table will be caused totravel to the rear end of the machine as shown in Figs. 1

and 2 when the power is disconnected. A

, sheet of metal of the desired length and width forming table,

placed in front thereof and the .is put into use.

is thenplaced upon the edge turning plate as shown in Fig. 2. A piece ofwooden molding or other piece of wood is then placed upon the metalbetween the stationary guide blocks 45 which are secured at one side ofthe and the pivoted guide blocks 46 which are secured by bolts 48 uponthe other side 'of the forming table. These blocks project over the edgeturning plate and bear against the edge ofthe wooden molding and alsoproject over the to of the wooden molding a short distance as siiown inFig. 3. Guide blocks 46 are connected at their rear ends by a link bar49 so that they can be operated together, and when the moldin is to belaced on the sheet of metal .these b ocks are t rown to the positionshown is placed on the metal these blocks are re turned to the positionshown in Fig. 2 and their further movement revented by stop blocks 50. Aspacing b ock 51 which is. a little shorter than the width of themolding anda little less in height than'the molding is sheet of metal isturned. upwardly against the same as shown in Fi s. 1 and 2. This blockis large enough so t at the metal which is formed aroundthe same will besuflicient for forming at that end of the molding when the molding Thefront end of the strip of metal is cut away as shown in Fig. 2. Power isapplied to cause the movement of the push bar and table toward the frontend of the ma chine, which carries the wooden molding and strip ofcasing metal therefor forward and the outer edges of the metal strip atthe front end thereof will first engage the upturned edges of theedgeturning plate and will be gradually turned thereby as it is pushedalong. The edges of the edge turning plate at all portions, except thefront are at right angles to the body and but little higher than thethickness of the metal used in casing. At

On power pulleywooden molding is the machine so they ously through dies,by .rear end of the wood, no marks and are curved and approach moreclosely together as shown in Fig. 2.

, As the molding and metal travel forward they passthrough aperture 52in forming die 53 which causes the metal to closely and snugly engagethe wooden molding. The further travel of the molding and the metalcasing thereforcausesit to pass through the finishing die 54 whichimpresses the edges of the metal into the wooden molding as shown at 55in Fig, 7, thereby locking the Just beforethe rear end of the moldingpasses throughthe forming die the motion of the push bar table isreversed and it runs to the rear of the machine and is stopped. othersheet of metal and another piece of laced and secured in the machine asbefore escribed, when motion is imparted to the machine to cause thetravel of the push bar toward the front end of themachine when the frontend of the second piece engages the rear end of the first piece andpushes the same on through the dies and out upon the reception table 56from which it is removed by an operator. The forming and finishing diesare removably secured in can be replaced'by dies of other sizes to fitthe difierent sized moldings. The forming table and edge turning plateare also removably secured in the machine so they can be changed fordifierent metal onto the wood.

sized moldings, it being understood that the edge turning plates andforming and finishing dies are used in sets, there being as manydifferent sets as there are different sized moldings to be finished.

By this method and machine it may be seen that a wooden molding can beincased with a metal sheet at one operation of the machine and withoutany partial preparation ofthe metal in any other machine, and that afterthe same is incased in-metal that no cutting away of any part isrequired, except the ordinary finishing of the ends, whereby waste oftime and material is avoided.

By the use of the spacing block, the required amount of metal isprovided for finishing the end of the molding or other piece of wood butif the end is not re uired to have a metal facing, the spacing b ockcould be omitted andthe front end of the metal would be appropriatelysecured to the front end of the wood. The spacing block forms aconvenient means where the end of the wood is to be metal faced forgaging the amount of metal for the end, and at the same time it providesmeans for securing the front end of the metal so that it will travelwith the wood through the dies. By this process, -which consists ofpushing the W00 "1 to be faced, and the metal that forms the facing,simultaneforce applied to the are produced on the finished piece of workand the forming up of improperly formed ends, such as is required whenthe work is pulled through dies,"

is avoided.

Having described my invention what I claim is:

die by pushing means applied to the-rear end of the wood.

' 2. The herein described method of putting;

' ona metal facing on wood consisting in securing the front ends of themetal for the facing and the wood to be faced'so that they will traveltogether, and then applying pushin means to the rear end of the wood andsimultaneously pushing the wood and the metalfor the casing thereofthrough a succession of dies adapted to form the metal upon the wood andembed the edge of the metal in the wood, whereby it is locked thereon. I

In witness that I claim the foregoing I have hereunto subscribed my namethis 13th day of June, 1907.
